SPECIFICATION forming partici Letters I'atent No. 653,162, dated July Y3, 1900. Application ined september 30,1899. "sen-a1 no. 732,137. (No man.)

This invention relates to wheeled cultiva` tors, and is designed in some respects as'an improvement on our Patent No. 615,7 7 5,dated December 13, 1898.

The object of this invention is to provide a seed-planter and cultivator of novel and peculiarconstruction and arrangement of parts, so that all the cultivator-beams and the seeddropping tubes have a vertical spring tention and the frame' carrying the cultivator implements may be tilted forward and held by special means from the shafts to raise the said implements from the ground, the wheeh axles acting as pivots in said tilting operation of the frame. It is also ourpurpose to provide a cultivator-frame to straddle two or more rowsone that may be `drawn by one, three, or more horses-and'to make such connections between the frame and plow-beams that the entire weight of the machine will be borne by the frame and wheels and not by the shafts or poles of the machine, and to provide means connected to the shafts for holding the frame, beams, and grain-tubes tilted forward, such tilting being effected without the driver leaving his seat on machine.

Other special and novel details are provided in our machine, whereby perfect-ion in construction and operation is produced.

AIn the accompanying drawings, forming part of this application, Figure 1 is a perspective view'ofthe machine. Fig. 2 is a front view of the frame, the wheels, and the draft-equalizer. Fig. o isa central vertical longitudinal section of the machine. is a detail view of one of the cultivator or plow beams and its controlling-spring. Fig. 5 is a detail view of one `of the seed tubes, means for hanging' it, and one end of the seed-hopper bar.' Fig. 6 is a side elevation of the machine held in tilted position. Fig. 7 is a detail section of `the axle-box. Fig. 8

the l Fig. i-

is a front view of-a frame adapted to straddle six'rows. l The samenumeral references denote the same parts throughout `the several views of the drawings.

The top 1 of the cultivator-frame is composed of angle-iron or has a vertical ange 1f" The ends of this frame portion are bent or turned downwardly to form an arch and terminate in an angle 2. The bottom of the cultivator-frame is composed of a single piece of iron, the ends 3 of whichI are, with the angles 2 of the top of the frame, bolted l to the axle-boxes 4. The axles 5 are secured in the boxes et to permit the wheels 6 to have a slight pivot movement relative to the frame,

so that the wheels'willfollow the angle of operated to keep the projections 7 iixed in a desired position.

From the ends 3 the lower frame iron is extended inward to form lower horizontal portions 10. From these portions the iron is bent upward at right angles to form vertical portions 11. From the top of these portions 11 the iron is bent to form top horizontal p0rtions 12, to which the top 1 of the frame is secured by suitable bolts or rivets 13. Then the iron is bent downward to form a central hanger composed of vertical members 14 and a cross member 15. The said slanting or downwardly-bent portions of the top frame form end braces between theportions 10 and 11 and brace the two frame portionstogether, so that there is no liability of the frame swaying, and all iiexibility is overcome.

Adjustablysecured to the frame portions 10 by bolts 16 are plates 17, having a pi'vot 18, and an upwardlyinwardly bent stop-piece 19. To these pivots 18 are pivoted the front forked arms of the outside plow or g cultivator beams 20, one offsaid arms 21 being extended forward under the stop-piece 19, which prevents the saidbeams from dropping down too far. The upward movements of the IOO - cross member 15.

said beams 2O are controlled by springs 21, having one end secured to the downwardlybent ends of the frame-top 1 and the other end secured to the arm 21. rlhe said beams terminate at the rear in diverging wings 22 and 23, the latter being longer than the former and each being provided with a stock 24, to which a plow or other suitable cultivator is attached. The stocks are adjustably hung from the beam-wings 22 and 23 by hangers 25.

The middle cultivator-beams 26 are of the same construction as the beams 2O and have the same character of stock-hangers and are secured to the cross member 15 of the central hanger with the same means and same stop projections as the outside beams 20, and the beams 26 are controlled by spiral springs 27. All of the plow-beams being controlled by the spiral springs, they are free to move vertically in accordance With the character of the ground upon which the machine is operated.

Connected to the top of the frame and standing in front of it is an angle-bar 2S, supported by arms 29. Seed-hoppers 30 are secured on the bar 28 and discharge into seed-tubes 31, pivoted at 33 to swing vertically on brackets 32. The discharge ends of the tubes are provided with guide-blades 34. The tubes are iexibly hung by means of hangers 35, depending from the frame, pivoted levers 37 and 38, and spiral springs 39, so that the tubes may have a flexible movement over the ground. The said hangers 35 have holes 40, by means of which and the bolts 41 they may be adj usted back and forth to vary the hang of the tubes, the same being covered by our application filed January 16, 1900, Serial No. 1,663.

The seat-post 42 is secured at one end to the cross-member 15 of the central frame-hanger, and the other end is pivoted to the forward seat extension 43, the latter being adj ustably pivoted to a vertical projection 44 from the By this arrangement the seat can be adjusted to throw the weight of the driver more upon the cultivator-frame or more upon the cultivator-beams, as desired.

A seed feed-shaft 45 is operated thron gh the seed-hoppers by the chain 46 and sprocketwheels 47 and 4S.

The tilting of the frame is accomplished by having the outer shafts 49 pivoted to the vertical frame portions l1, the inner shafts 45a being pivoted to the vertical members 14 of- 15, his position thus assisting the forward tilt of the frame and beams as he leans forward. The outer shafts 49 have rings 49 for other draft attachments, such as single or double trees.

It is essential that the draft be equalized in this form of cultivator, so that the machine maybe more perfectly operated and the plows not thrown from the rows by unequal draft. We therefore provide a draft-equalizer which comprises the levers 54 and 55, pivoted together at 56, the former being pivoted to a plate 57, adjustably secured to the frame-top 1, and has a yoke 5S swiveled thereto, and the latter is pivoted to a plate 59, adjustably secured to the under side of the cross member 15 of the central frame-hanger. From the yoke 58 extends ropes, cables, or chains 60 through eyes 61 (or pulleys in lieu thereof) on the top and downwardly-bent frame portions. The ropes 60 have singletrees 62 attached, and the lever 55 has a like singletree 63 attached, so that a perfectlyequal draft is accomplished, the same being covered by our application filed January 16, 1900, Serial No. 1,664.

In lieu of the shafts we may employ a pole 64, having side members 65, provided with tnrnbuckles 66 for adjusting the pole to the right and left of the machine, so that the horses may travel at an angle to the machine.

Referring to Fig. 9,' the bottom portion of the frame is bent into a series of hangers 67,

for the purpose of attaching plow-beams, one or two beams to each hanger.

It is obvious that many slight changes may be made in the practical application of the machine to effect the best results without departing from the spirit of our invention.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. A cultivator frame composed of two parts, the top part having ends terminating in angles, and the bottom part being formed into vert-ical and horizontal portions Which terminate at and are secured to the said angles, said top part having downwardly-slanting members which form braces between certain of the said vertical and horizontal portions.

2. A cultivator-beam having a forked front end, one of the forks being longer than the other, and diverging rear Wings adapted to carry a plow or other cultivator.

3. The combination, with the cultivatorframe, of the cultivator-beams having a forked front end pivoted to the frame, a spring attached to the extended end of the fork forward of the said pivot and connected to the said frame to give the beams exibility, and the stops engaged by said extended fork ends to control the downward movement of the beams.

4. The combination, with the frame, and the axles attached thereto to form a tilting pivot for the frame, of means for holding the frame tilted, comprising the shafts having an upward projection, a hand-lever pivoted to IOO IIO

the said projection, and a hook on the said lever adapted to engage J[he top of the frame, as set forth.

5. Themcombination, with the frame, and the pivoted plates adjustably secured to the frame and 'provided'with stop projections, of the cultivator-bearns having rear diverging wings, and a front fork pivoted to said plates to move. vertically, one member of the said fork being extended under the said stops to control the downward movementof the beams, and a spiral spring having one end attached to the end of the extended fork member and the other end secured to the frame, to control the upward movement of the beams.
